Bizarre declaration

[Shalini Srivastav]

interface Bounceable{};
class MyClass{};

Any comment about it ?

Context? Why is this something you or we should bother with?

I never used colon after declaration of classes or interfaces lol.

A semi-colon indicates the end of a statement or line of code in Java, even an empty one.

The second line of your post is the same as,

class MyClass
{

}
;

An empty class, MyClass, followed by an empty line of code.
